First Site?
Is this the first webpage that you've designed? If so, it's not bad! I see by your HTML that you used Serif WebPlus. I am not too familiar with the program.
If you like the way it looks, I'd focus on touching up some minor details, as some others have pointed out: play around with the text until you find a size and font that fit. I'd recommend a smaller font when typing long paragraphs. I strongly dislike the row of buttons on the top. To me, the buttons seem stretched out so that they span the entire page.
Look around the web for ideas on design. Even, for example
http://www.serif.com/, you can see that their buttons along the top are not stretched out all the way. I would also avoid putting drop-down menus on your buttons unless they really do have a lot of choices for each (as in the Serif site).
Also (as in the Serif site), there is cell padding between the border of the large table and the text and images within the table. Consider putting more space there. You don't need much, but keep it consistent throughout the whole page.
Remember, most users don't read all the paragraphs on each page unless they are very interested in what you have to say. This depends on the individual user. Design the site so that most customers will be able to get the important information first, without having to travel far to look for it. Think of newspapers. Which stories appear above the fold, and which appear below?
Good luck, and thanks for asking us to critique your webpage.
